Cogswell 1949 Empidonax wrightii Aug. 20 3200 ft., Humboldt Co. Calif. Near the same spot at which I collected an Opornis tolmeici (see account of that species for description of vegetation) there were 3 Empidonax flycatchers. Two stayed well within the branchwork of the tan oak + chinquapin bushes near the ridge top, calling persistently: "ks-zeell---pit-----ks. zeell", etc. I caught only glimpses of them. The other one perched about the lateral margins of the shrub canopy, on nearby low snags, and twice flew up into outlying branches of the nearby dead Douglas firs. It called a simple "pit" at intervals of about 2 secs for a while, then was silent, then resumed this calling. It was finally collected, and a brood patch noted on its belly. I think the two in the shrubbery were its young. 10:30 a.m. Found the young ones fluttering from bush to bush in more open area with no salad near the above spot. They were calling yet, a rendition might be closer to : "pit ---- kizick ----- kizick kizick", etc. I collected one of three young ones observed. A bit later at the border of the burnt forest (now regrown to chinquapin & tan oak) about 150 ft. alt. below the ridge top on the SE-facing side I saw another family of young being fed by at least 1 adult.
